What is systemFilesDirtyBitStatus?
This read-only OID is a bitmask (0–4096) showing which system files have unsaved changes and need to be written to disk. You monitor this during system startup to verify the boot process completed successfully and all critical files are synchronized. A value of 0 means all files are clean; a value of 5 means both console.def and ssid.def have pending changes.
